One Million BBY

For this month's submission, I decided to draw my two favorite pieces of design from the prequels - the Acklay and the clones. I always thought Star Wars needed a good crab monster, and those fins on the clone helmets, SO PULP. I love it. I decided to roll it all into a Ray Harryhausen tribute, because why the hell not??

Bonus points if you know what movie this is an homage to (hint: it's not actually One Million BC)
